New Almaden Quicksilver Mine-mining-era legends and reports

The New Almaden mining district in San Jose was the site of California's first and most productive mercury mines in the 19th century, now preserved as Almaden Quicksilver County Park and the New Almaden Quicksilver Mining Museum. The park's ruins and museum have been focal points for local folklore about miners' ghosts, unexplained lights, and other reported phenomena documented in regional folklore collections and local media. These stories are part of local tradition and are treated as anecdotal rather than scientifically verified.
